Abstract

A directory structure that may allow concurrent processing of write-back and clean victimization requests is disclosed. The directory structure may include a memory configured to store a plurality of entries, where each entry may include information indicative of a status of a respective entry in a cache memory. Update requests for the entries in the memory may be received and stored. A subset of previously stored update requests may be selected. Each update request of the subset of the previously stored update requests may then be processed concurrently.
